HESI A2 Vocabulary 2023

Correct Answer: A

Rationale: The correct answer is A: Ripple. In this sentence, 'undulate' is used to describe a smooth, wave-like motion of the muscles, which aligns with the meaning of 'ripple.' The word 'undulate' implies a continuous and flowing movement, resembling the gentle and rhythmic movement of waves. The other choices, shake, flatten, and unknot, do not capture the specific fluid and continuous motion described in the sentence. 'Shake' implies a more abrupt and irregular movement, 'flatten' suggests a completely different action of making something flat, and 'unknot' refers to the action of undoing a knot, none of which fit the context of the sentence.

Correct Answer: C

Rationale: The correct answer is C: full. Replete means filled or well-supplied with something. In this context, it refers to being completely full or satisfied. Choice A (hardy) does not convey the same meaning. Choice B (quiet) and choice D (sad) are unrelated to the definition of replete, making them incorrect. Therefore, C is the best fit as it directly aligns with the definition of the word.

Correct Answer: A

Rationale: The correct answer is A: A test of brain activity. EEG stands for Electroencephalogram, which is a test that measures electrical activity in the brain. This test is commonly used to diagnose epilepsy, sleep disorders, and other neurological conditions. Choice B is incorrect as EEG is not a service but a diagnostic test. Choice C is incorrect as EEG does not monitor heartbeats. Choice D is incorrect as EEG has no relation to dentistry. EEG specifically focuses on brain activity, making choice A the most appropriate description.

Correct Answer: C

Rationale: The correct answer is C: Reaction. In the context of the sentence, 'reflex' refers to an involuntary and nearly instantaneous reaction to a stimulus. The patellar reflex mentioned involves the leg extension in response to a tap on the patellar tendon. Replication (A) does not fit the context as the sentence is not referring to duplicating something. Convulsion (B) implies a violent, involuntary contraction of muscles, which is not the focus here. Stretching (D) is not the correct choice as it does not capture the immediate and automatic nature of a reflex action.

Correct Answer: D

Rationale: The correct answer is D: Bond. Rapport refers to a close and harmonious relationship or connection between individuals. In the context of the sentence, 'developed a quick rapport' implies that the nurses and teenage aides quickly formed a close bond or connection. This is evident through their ability to communicate effectively, trust each other, and work well together. Choice A: Performance is incorrect because rapport does not refer to performance but rather the relationship between individuals. Choice B: Narrative is incorrect because rapport does not relate to storytelling but rather the bond or connection between people. Choice C: Manner is incorrect because rapport is not about the way something is done but rather the quality of the relationship. In summary, the word 'rapport' in this sentence specifically means a bond or connection between the nurses and teenage aides, making choice D the correct answer.
